Question about ALA conferences

I just read an interesting article in the online Chronicle about childcare at academic/industry conferences. I must admit, the thought of this issue has never crossed my mind before. Even though I have plenty of colleagues and librarian friends with children. So let me ask the floor--> Is there a big need for onsite childcare at large library conferences, such as ALA or ALA MW? (What about small ones, like OCLC Members Council meetings?)

I guess I had always assumed that if you had young kids, you left them with a trusted spouse, parent, family member, etc. and came anyway. With today's phone conferencing, video and podcasting options, you can worst case attend remotely if the conference organizers know you are interested and they're willing to work with you.

Still, I'd be curious to know what libraryland thinks of this issue. Do we as an industry need to consider childcare at our conferences?
